Each of those articles were at different dates stupid.
So the % varied, but they were all over 51% ,
China has had Over 51% for more than a Year, which each of those articles Prove
Guys, calm down a little, please
The question is not so much about what exact percentage of hashing power the Chinese miners are controlling at the moment, though everything shows that they do already control substantially over 51% of it. In any case, the Chinese government can at any moment pour enough resources (which they have with a vengeance) into mining if they think it worth the effort, and grab as much hashing power as they see appropriate. The questions which I think worthy of debating here are as follows:
1. Could the miners potentially make the transactions coming from the US substantially more expensive than all other transactions, or even totally discard them?
2. Is it ever possible to circumvent such discrimination should it happen for real, and if it is doable, what can be done exactly?
Let's assume that the Chinese authorities do control Bitcoin mining, and they are eager to retaliate in the way I described (e.g. through raising fees)

Easily thru approved address lists, any address not approved would be charged the higher rate.2. Is it ever possible to circumvent such discrimination should it happen for real, and if it is doable, what can be done exactly?
Sadly No, China is the main Industrialize Nation of the world , the Main Fork they will Control Forever.
The rest of the world could create a new hard fork , and fork away from them, but since they are the main ASICS manufacturers, they will easily be able to take over than fork too.
Their is only 1 way to remove their control, that is to remove ASICS from the equation,
Proof of Stake is ASICS resistant and even if someone owes 51% of a PoS Coin, as long as it has over 15 days between staking , they will not have control long enough to block transactions more than a short amount of time. As with PoS Mining % is always in a flux state from one stake to the next.
(Any way that is my solution, maybe so one will come up with another one.)
